TMT Bars

ASR THERMEX TMT Bars assures your dream construction an ability to stand tall and protect you even in the time of natural calamities.
Mild Steel TMT Bars offered by our company are known for their durable performance and resistance against adverse conditions. We make available these T Bars in different sizes and dimensions depending on clients� requirement.

The careful removal of slag during the boiling process results in highly purified form of Billets. At the exit of the rolled product, the ribbed bar is subjected to the Thermo Mechanical Treatment (TMT) process across 3 stages.
  
Stage 1: This involves successive steps of rapid quenching in a special water system converting the surface layer of ribbed bar into a hardened structure.
  
Stage 2: This is tempering process, which involves the flow of the heat from the core of the bar to the surface.
  
Stage 3: Finally, the bars are cooled in atmospheric air on the cooling bed. Because of the sudden and extensive cooling of the red hot bar, its temperature lowers down from 1000� Celsius to 300� Celsius. The process turns the periphery of the bar hard but the core of the bar remains largely unaffected. On the cooling bed, the inner hot zone reheats the bar and anneals its surface. This tempered hard surface is termed as �MARTENSITE� and inner soft core is called �FERRITE-PEARLITE�. The brittle-free, hardened and elastic state of these bars, make it capable to survive even high magnitude earthquakes
